Power transmission line ground clearance lifting cross arm
The invention relates to a power transmission line ground clearance lifting cross arm. The distance between a wire and the ground cannot meet the requirement of 7.0 meters due to a cushion road in a 35kV line protection area. The power transmission line ground clearance lifting cross arm comprises an upper hoop (3), a lower hoop (5) and a hoisting frame, wherein the upper hoop and the lower hoop are fixed through pulling plates (4), sleeve lugs (8) are arranged on the front side surface and the rear side surface of the upper hoop and the front side surface and the rear side surface of the lower hoop respectively, and vertical plates (6) of the hoisting frame penetrate through the sleeve lugs (8) of the upper hoop and are fixed through bolts; and the lifting frame comprises four vertical plates, every two of the four vertical plates form a group and are arranged front and back, and the upper parts of the four vertical plates are welded and fixed through a square ring sleeve (1). The lifting cross arm is used for lifting the ground clearance of the power transmission line.
输电线路离地间隙提升横担。35kV线路防护区内垫道造成导线对地距离不能满足7.0米的要求。本发明组成包括：上抱箍（3）、下抱箍（5）和提升架，所述的上抱箍与所述的下抱箍通过拉板（4）固定，所述的上抱箍和所述的下抱箍的前后两侧面分别具有套耳（8），提升架的立板（6）穿过所述的上抱箍和所述的下抱箍的套耳（8）并且通过螺栓固定，所述的提升架包括四个立板，四个所述的立板每两个为一组前后布置，四个所述的立板的上部通过方环套（1）焊接固定。本发明用于输电线路离地间隙提升横担。
